Help, homework is due tomorrow, it belongs to my nephew

#1:  3t + -6,     #2:  0.2y + 0.2(2) = 0.2y + 0.4

Might help to understand why expanding works.

Multiplication is just repeated addition. 4 x 3 is the same as saying 4 + 4 + 4. So when we say 3(t - 2), we're really saying

(t - 2) + (t - 2) + (t - 2).

And if you remove the parentheses and rearrange it, you get

t - 2 + t - 2 + t - 2

t + t + t - 2 - 2 - 2

(t + t + t) + (-2 + -2 + -2)

3t + 3(-2).

Does that make sense? Drawing a picture can help too:

Anyway so for #1 we have 3(t - 2), which equals 3(t) + 3(-2), which is 3t + -6.

For #2 we have 0.2(y + 2)  =  0.2y + 0.2(2)  =  0.2y + 0.4.

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
